(1) Apply pre-req patches ( see note I pointed out ) (2) clone your current web node onto another node. (3) set up the balancer hardware + open the ports etc and list the two web nodes in its hosts table. (4) set the name of your load balancer in dns etc to say 'myweblb01' ( my web load balancer 01 ) (5) Change the context file on each node .. web entry points etc .. see note pointed out below to point to myweblb01 (6) Run autoconfig (7) ... fix any issues htat may come up .... ( like the potential for reverse name lookup errors in your logs - which will happen if you use virtual node names instead of physical ones ) etc. If you need ton know more on how to set up the lb hardware itself, then that will be hardware specific. I.e. are you using BIG IP, load director etc etc -----Original Message----- From: ora-apps-dba-bounce@xxxxxxxxxxxxx [mailto:ora-apps-dba-bounce@xxxxxxxxxxxxx] On Behalf Of Fadi Hasweh Sent: 19 June 2006 09:02 To: ora-apps-dba@xxxxxxxxxxxxx Subject: RE: Apps Advanced installation Thanks kent for prompt reply I will check and get back to you. I have hardware load balancer already but I don't know how to do more than one web node installation Thanks again Any hint on how to do the installation will be helpful. fadi _____ From: ora-apps-dba-bounce@xxxxxxxxxxxxx [mailto:ora-apps-dba-bounce@xxxxxxxxxxxxx] On Behalf Of Rolfe, Kent (GTI AIS OPS/SE) Sent: Monday, June 19, 2006 10:57 AM To: ora-apps-dba@xxxxxxxxxxxxx Subject: RE: Apps Advanced installation Yes - its standard practice in every place I have worked ( where I am currently has 4 web front ends ). But, whilst Apps can balance itself, you are much better off with a hardware load balancer to do the work for you. If you are doing this on a company scale ( i.e. not just testing yourself ) then I would definitely say to get a hardware ( as opposed to software ) load balancer. If you are testing for yourself, you have two options .. (1) Download a free software load balancer from the net ( there will be a few around ) or (2) start trying to do the 'apps version' which, well, is not fully balanced and is flawed in a few respects. If you are running SSL, then I would get a hardware load balancer that includes an SSL accelerator. Because, otherwise you start getting issues with your balancing due to the inability of the balancer to interpret the packets ... i..e it then needs to keep the stickiness based on the IP that originated the request. Also, the SSL accelerator will offload the CPU overhead onto the accelerator from the web nodes. Assuming you are not going for the Apps version ( I dont know anyone who uses that ) - its just a matter of either (a) changing your context file and running autoconfig on each web node or (b) Changing a few profiles and the Apache config files. Basically, you would have each node being say web1 and web2 and you would have your balancer to be called 'web'. Then, your profiles point to 'web' instead of web or web2. You then may want to, on each of web1 and web2, put and entry in the hosts file for itself to point to web. That allows reverse name lookups and internal name resolution ( like workflow formatted emails ) to be quicker. There must be something on metalink somewhere.... in fact just looked this up .. start with reading 217368.1 BTW - I would not look at Jserv load balancing. I spent some time playing with that and, unless you are looking at using cheap linux boxes, I did not find any great reason to go for that.
